Hamburg SV striker Naohiro Takahara will join Japan's Olympic team training camp being held on Ishigaki Island in Okinawa, Japan Under-23 coach Masakuni Yamamoto said Wednesday.

Takahara, who has just recovered from deep vein thrombosis, the same illness that kept him out of the 2002 World Cup, will join up with his teammates on Wednesday evening but will go through a separate training program.

The 25-year-old Sydney Olympian has been selected as one of three "over-age" players to take part in next month's Athens Olympics.

Japan face Tunisia's U-23s in a pre-Olympic warm-up match at Toyota Stadium in Aichi Prefecture on July 14.
